A. In each _____________ of the anther are masses of ______________ (diploid microspore mother cells). B. Each of the diploid cells divides by meiosis to form four haploid cells called ______. Mitosis of the haploid cells forms a pollen grain with two nuclei. One nucleus called the _________ creates a passageway for the gametes and the other nuclei called _________ produces the gametes. C. Prior to fertilization in the angiosperms, pollen grains are released from the _________ of the flower to land upon the __________ of the same or another flower. This process is called ________. D. Inside the ovule, a(an)_________ with a diploid (2n) chromosomal condition divides by ___________ forming four _____________, only one becomes a(an) embryo sac and develops into a(an) ___________ after fertilization. E. In the female gametophyte of the ovary, one egg is associated with the __________ which is located at the __________ end. F. In the angiosperms, ____________ develops from the outer layer of the ovule while a(an) __________ develops from the outer wall of the ovary. G. In the corn seed, the _________ refers to the thin layer of fused __________, mesocarp and endocarp. H. Aggregate fruits develop from separate _____________ ovaries of a(an) __________ flower e.g. strawberry, Annona squamosa (atis).
